Question

What are the three types of chromosomes as to centromere location? Describe each.

Answer 1

Answer:

On the basis of the location of the centromere, chromosomes are classified into four types: metacentric, submetacentric, acrocentric, and telocentric. As previously mentioned, the centromere is easily visualized as the most constricted region of a condensed mitotic chromosome.

Answer 2

The type of chromosomes based on the position of centromere are of the following four types :

1) Metacentric chromosome: centromere in middle forming two equal arms.

2) Sub-metacentric chromosome: centromere placed near to one end resulting in one shorter and one long arm.

3) Acrocentric chromosome: Centromere placed close to one end forming one extreme short and one extreme long arm.

4) Telocentric chromosome: terminally placed centromere.
